I bought the game (supercharged edition) and i had the demo already installed. I tried to log in on it but it just went into the demo. I also tried downloading again from where i activated the key and it also just put me in the demo version. I need help!!
Click on “Play Game” instead pf “Play Demo” in the Launcher, after you filled in your username and password. 
That’s the thing. I already did that.
Then you probably confuse what should be in the game at this point of time: if you have I6s and V8s then you are indeed running the full version. The game is still in development and most features aren’t completed yet. Cheers!
Wait i was just stupid. I thought that the singleplayer thing would open when you bought the game. False alarm
